AC112 / ACH112
Brazed Plate Heat Exchanger
General information
Alfa Laval introduced its first brazed plate heat exchanger in
1977 and has since continuously developed and optimized
its performance and reliability.
Brazing the stainless steel plates together eliminates the
need for gaskets and thick frame plates, which makes the
heat exchanger compact and saves material. The brazing
material seals and holds the plates together at the contact
points ensuring optimal heat transfer efficiency and pressure
resistance. Using advanced design technologies and
extensive verification guarantees the highest performance and
longest possible service lifetime.
The AlfaChill (AC) brazed plate heat exchangers are specifically
designed for heat transfer in air conditioning, refrigeration and
heat pump applications.
Innovative features for this single circuit heat exchanger
include a pipe distributor for efficient distribution throughout
the plate pack as well as a patented asymmetric plate design.
The plate design provides the flexibility to select the best
configuration for optimized evaporation temperature and/or
condensation temperature in order to keep the brine/water
pressure drop at the desired level.
Typical applications
.
- Evaporator and condenser in high efficiency chillers
- Evaporator and condenser in A/W, B/W, W/W heat pumps
- Economizer in chiller and heat pumps
The standard design supports a wide variety of HFC
refrigerants such as R407C, R404A, R507, R134a. The
high-pressure version is suitable for R410A, R32 and natural
refrigerants (CO2 - propane).

Capacity range
AC112/ACH112 cover capacities from 30 kW up to 200 kW
(10-60 RT). Based on standard components and a modular
concept, each unit is custom-designed for each specific
installation.
